Please help! what is the cause of appearance of fused ear lobes in some persons against the progression of evolution?

In brief:
That's silly

Evolution doesn't proceed in any particular direction.

This is such a basic misunderstanding that if you heard it from a biology instructor, you should report that individual to their supervisor. It's the natural tendency of living things to differ from one another, more or less randomly. Please, to be literate in the 21st century, get a good book to understand basic biology.
